but even if you do get one alexh, what will happen when the next game u pop in asks for an update?

In the future, they wont ask for updates. Why? Because now it is possible to patch games to remove such checks because you can run unsigned code.

I think Keropi is right, there is already homebrew route but it arrived too late, was difficult to use and too many people had updated beyond a vulnerable kernal. The result was two years of no work on XBOX 360 homebrew.

Just a shame that they released the information about how it was going to work before there was a working implementation and a way to patch the OS & games to remove updates.
